SPECIFICATION forming part Of Letters Patent N 0. 656,399, dated August21, 1900.

Application filed February 21, 1900. Serial No. 6,051. (No model.)

To a whom, it may concern:

Be it known that I, POLK H. FLOW RS, a citizen of the UnitedStates,'residing at Gen treville, in the county of Hickman and State ofTennessee, have invented certain new and useful Improvements inEyeglasses; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to certain improvements in eyeglasses, and moreparticularly to certain improvements in mountings for eyeglasses; andthe objects and nature of my invention will be obvious to those skilledin the art in view of the following description, which refers forpurposes of illustration to the construction shown in the accompanyingdrawin gs as an example among other devices within the spirit and scopeof my invention.

This invention consists in certain novel features in construction and incombinations and arrangements of parts and details, as more fully andparticularly pointed out and described hereinafter.

Referring'to the accompanying drawings, Figure 1 is a front elevation ofa pair of eyeglasses mounted or the frame of which is constructed inaccordance with my invention.-

Fig. 2 is an elevation of one lens, the connecting-spring beingpartially broken away and the nose-guard, spring, and stud being shownseparated, with the clamping pivot-screw removed and shown in elevation.Fig. 3 is an end elevation of the pair of eyeglasses, dotted linesshowing the parts adjusted to different relative angles or positions.Figs. 4,5, and 6 are detail views.

Difficulty is experienced by the Optician in properly applying theeyeglasses at present the impossibility of adjusting the relative anglesor positions of the lenses, spring, and nose-guards or the relativeangle or position of the lenses and nose-guard independently of andwithout changing the relative position of the spring. The Optician isnow generally obliged to carry a large stock of various styles of framesor eyeglass-mounts in order to fill various prescriptions and meet andsupply the widely-varying conditions and wants of different patients.

It is an object of my invention to provide a mount or frame foreyeglasses so constructed and'arranged that a pair of eyeglasses can beadjusted to fill any prescription and to properlyfit the nose of anypatient,with the lenses arranged and located properly before the eyesand the spring properly located with respect to the forehead, byproviding peculiar means in fitting the ordinary glasses it often happens that when the guards and lenses are properly located with respectto the nose and eyes the spring will press against the forehead; also,the lenses can be independently adjusted to the proper position withrespect to the eyes, for in fitting the ordinary glasses it oftenhappens that when the guards and spring are located as desired thelenses will be inclined or otherwise objectionably located with respectto the eyes or line of vision.

In the drawings, a a, are the lenses, which can be provided with rims ornot, as found most desirable, although in the drawings for the purposesof convenient illustration I show the lenses without surrounding rims orframes and having the studs a secured to the inner ends or sides of thelenses in any suitable and desirable manner. These studs projectinwardly, as usual, and each has a threaded hole tapped longitudinallythereinto, while the Outer end of the stud is formed approximately fiator plane to constitute a bearing seat or face, and said bearing seat orface is preferably formed with the series of radiat ing (or otherwisearranged) notches or serrations (see a") around the said screw-hole.

b is the connecting-spring, which can be of any suitable and desirableform and construction and is provided with the end eyes or contrally-perforated end heads I), the perforations of which register,respectively, with the threaded holes of said studs and the outer fiatfaces of which fit and bear against the the ends of the studs, so thatsaid parts can be held and locked against independent turning orrocking, as hereinafter more fully set forth.

0 indicates the nose-guards,each preferably;

although not necessarily, consisting of an oblong or elongated padprovided with a suitable back, frame, or holder of any suitable anddesirable construction.

c c are the arms or holders for said pads and forming parts of thenose-guards. Each arm 0 consists, preferably, of a flexible metal Wireor rod usually circular in cross-section and preferably attached rigidlyto the back of a pad about at the center of the length thereof 4 andextending laterally therefrom. The opposite end of each arm 0 is formedwith a perforated head 0, the inner face of which is preferably formedwith radial teeth, serrations, or notches to coincide and intermesh withthe corresponding notches at the outer face of a spring-eye. The outerface of each eye 0 is usually smooth, although my invention is not solimited.

d d are the headed pivot clamping-screws. Each screw passes through anose-guard eye, a spring-eye, and into a stud, and by tightening thescrew its head bearing against the smooth outer face of the nose-guardeye will ;-clamp the said various parts together, with theirlocking-notches intermeshing, and thus tightly hold and lock the partstogether against independent axial movement on said screw. When eitheror both screws are loosened sufficiently to permit such movement of aguard, lens, or the spring as to free its locking-notches from thenotches of adjacent parts, then said part can be freely rocked or turnedto the desired angle on the clamping-screw as a pivot. When the partsare thus loosened,.the spring can be swung in either direction, thelenses rocked to the desired angle with respect to the spring or guards,and the guards can be set as desired. When the screws are tightened,said parts are rigidly locked in the desired relative positions and arefirmly held by the intermeshing notches or other locking means Withinthe scope and spirit of my invention which might be employed as theequivalent of said notches. In practice when it is desired to adjust apart a screw can be loosened slightly, so that the notches will barelyspring or slip past each other. I also attain material advantages byconnecting or mounting the nose-pads in the manner described by flexiblewires, as the wire arms or connections can be thuseasily bent or loopedto draw the nose-guards toward or from the plane occupied by the lensesto raise or lower said guards or to set the same at any desired angle.In the drawings I show a few of the many adjustments which can beobtained by means of said flexible arms, and the number of possibleadjustments are increased by securing the flexible arms about at thecenters of the lengths of the pads, as the pads can thereby be rocked ontheir centers, as is obvious to those skilled in the art.

It is evident that various changes might be made in the forms,constructions, and arrangements of the parts described without departingfrom the spirit and scope of my invention. Hence I do not wish to limitmyself to the exact construction shown and described.

Having thusfully described my invention, what I claim as new, and desireto secure by Letters Patent of the United States, is-

1. In eyeglasses, the combination of the lenses having the studs, thespring having the end eyes seated against said studs, the nose guardshaving connecting arms provided with eyes seated against saidspringeyes, the clamping-screws passing through said eyes into thestuds, said spring and guards being independently movable axially onsaid screws, said eyes and studs provided with locking means,substantially as described.

2. In combination, the lenses having the studs formed with notched ends,the spring having eyes formed with notched faces seated against saidnotched stud ends, the noseguards having connecting-arms provided withend eyes seated against said spring-eyes and having correspondingnotches, and the clamping pivot-screws passing through said eyes intothe studs, substantially as described.

8. In eyeglasses, the combination of lens studs or supports, theconnectingspring, nose guards having supporting arms, and pivotclampingscrews locking said arms, spring and lens supports together,said spring having eyes through which said screws pass, the parts beingso constructed and arranged as to permit rocking of thespringindependently of the lens-supports and noseguards, when the screwsare loosened, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.
